摘要：A current sensor includes a magnetoresistance effect element in which aplurality of magnetic detecting portions and a plurality of permanent magnet portionsare alternately arranged so as to be in contact with each other. Each magnetic detectingportion is configured to include a ferromagnetic fixed layer whose magnetization

direction is substantially fixed and a free magnetic layer whose magnetization directionchanges with respect to an external magnetic field. Each permanent magnet portion isconfigured to include a hard bias layer applying a bias magnetic field to the free magneticlayer. An interval between the adjacent permanent magnet portions is 20 μm to 100 μm.
